Coal mine continuous miner KSW-1500EU1

KSW-1500EU1 is a double ranging arm shearer with electric haulage drive. The shearer is carried along the length of the face on the armoured face conveyor (AFC) in a chainless haulage system. The shearer route is 860–1100 mm wide. It is designed for bidirectional cutting and loading coal in a longwall mining system. KSW-1500EU1 is adapted to longwall mining operations in seams inclined up to 35° longitudinally, up to 20° transversely (upwards) and up to 12° transversely (downwards). Haulage of KSW-1500EU1 is provided by two haulage units. Each of them is driven by a three-phase asynchronous motor powered from frequency converter installed on the shearer. The frequency converters enable a smooth control of output frequency in the range of 0-120 Hz what results in a continuous control of shearer haulage speed from 0 to 36m/min.
